Steam-radiator cock



UNITED STATES PATENT OFFICE.

STEPHEN J. GOED, OF NEW HAVEN, CONNECTICUT.

STEAM-RADIATOR COOK.

Specification of Letters Patent N o. 14:,5007 dated March 25, 1856.

To all whomz't may concern Be it known that I, STEPHEN J. GOLD, Of the city and county Of New Haven and State of Connecticut, have invented a new and useful Improvement in Radiator-Cocks for Steam-Heating Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, forming part of this specification, in which- Figure l is a cent-ral section through axes 'i of discharge channel. Fig. 2 is a head view cap perforation. Fig. 3 is a head view with cap removed.

Similar letters of reference in the several figures denote the same part of the cock.

The invent-ion here considered is designed tO be used in connection with the radiators patented by me Oct. 3d 1854. Its Object is the automatic closing Of the air passage when the radiator is filled with steam.

It consists in the insertion Of a metallic disk in the head Of the cock, slightly smaller than the cavity containing it, and with a small space between the outer face Of the disk and the inner face of the cap, which surfaces are ground so as to insure contact when t-he disk is pressed against the cap. The details of construction and Operation are as follows.

A is the portion of cock screwing upon discharge tube Of radiator and B the mOvable portion of the cock. C is the cap,

screwed upon portion B of cock, and provided with an opening a for t-he exit of air. The inner surface of cap C is ground as fiat as practicable. f is a disk of metal, either flat on both faces, Or flat at top and concave On the under side; the top being ground flat. This disk is of less diameter than the cavity containing it, and when the cap is in position there is a slight space between the inner surface Of the cap and the ground face of the disk.

c is the channel of the cock.

The operation Of this cock is as follows:

'The space between the disk, f, and cavity containing it will admit of the discharge of air from the radiator as the radiator fills with steam. When however, the radiator is full, and steam passes into the small space between the disk and cap, it is at Once condensed and forms a film Of water uniting the accurately formed faces O-f cap and disk, and thus causing the pressure behind the disk to keep it closely against the cap, and eifectually prevent the egress of steam. When the pressure is removed by the radiator becoming empty, the disk falls from its contact and air is admitted at a.

vWhat I claim as my invention and desire to secure by Letters Patent, is-

The automatic closing of t-he cock onthe lling of the radiator with steam, by means Of a loose disk in the head of the cock, acted upon substantially as set forth.

In testimony whereof, I have hereunto signed my name before two subscribing witnesses.
